NJU6312 Series
0.9V Operation Fundamental Quartz Crystal Oscillator IC for Flip
!GENERAL DESCRIPTION
The NJU6312 series is C-MOS quartz crystal oscillator IC
for fundamental (up to 80MHz) oscillation.
The pad arrangement suitable for flip die mount simplifies
development of small-sized oscillator.
The operating voltage is from 0.9V to 3.0V, and the pad
layout is for flip die based on smaller ceramic package.
The 5-stage divider generates only one frequency selected
of f0,f0/2,f0/4 f0/8, f0/16 and f0/32 by internal circuits is output.
The oscillation amplifier is realized very low stand-by
current using NAND circuit.
Furthermore, The 3-state output buffer is C-MOS
compatible.
